LINE + GRADIENT CONDENSER MICROPHONE
- Designed for video production and broadcast (ENG/EFP)
audio acquisition
- Extremely short length (175mm) ideal for use with compact
digital cameras
- Provides the narrow acceptance angle desirable for long-
distance sound pickup
- Excellent sound rejection from the sides and rear of mic
- Tailored response minimizes camera and handling noise
- Operates on phantom power only
The AT875R requires 11V to 52V DC phantom power for
operation.
Output from the microphone’s XLRM-type connector is low
impedance (Lo-Z) balanced. The signal appears across Pins
2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot” –
positive acoustic pressure produces positive voltage at Pin 2.
To avoid phase cancellation and poor sound, all mic cables
must be wired consistently: Pin 1-to-Pin 1, etc.
The high sensitivity of the AT875R assures useful output and
an excellent match to most input sources. In some cases,
however, an attenuator such as the Audio-Technica AT8202
may be required between the microphone and preamplier to
avoid overloading sensitive input stages.
The microphone is RoHS compliant–free from all substances
specied in the EU directive on hazardous substances.
Avoid leaving the microphone in the open sun or in areas
where temperatures exceed 43°C for extended periods.
Extremely high humidity should also be avoided.

- 十分短的长度设计(175mm)，适合于小型数字摄像机使
用。
- 提供窄角度的超指向性能，给与远距离的收音效果。
- 由话筒两旁到后方均有极佳抗噪音能力。
- 特有的频率响应，可减低摄像机和手持噪声。
- 使用幻象供电工作。

为 避 免出 现 相 位相 互 抵 消而 失 真 的 情况 ， 所 有话 筒 连 接
时，接线必需以1-1，2-2，3-3型式把针脚连接。
AT875R提供高灵敏度的收音效能，可确保能接收到最大
